We're dividing 85080999 by 154 
We want to divide 85080999 by 154.

Step 1:
The number 154 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 154

Moving on to step 2:
When dividing 85 by 154, we get 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Take the next digit (0) from the dividend and append it to 85, then repeat: 850 / 154

Moving on to step 3:
154 can be fit into 850 5 times, resulting in a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 80 after subtracting 770 from 850.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 154

Moving on to step 4:
The number 154 fits into 808 5 times, leaving a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
If we take 770 away from 808, we end up with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 154

Step 5:
154 goes into 380 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 552.0
Deduct 308 from 380 and we're left with 72.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 154

On to step 6:
154 goes into 729 4 times with a remainder of 113.
The number 4 becomes the next digit in our result. 
Result so far: 5524.0
If we subtract 616 from 729, we get 113.
Append the next digit (9) from the dividend to 113 and continue with: 1139 / 154

Step 7:
154 goes into 1139 7 times with a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 55247.0
The remainder is 61 after subtracting 1078 from 1139.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 154

Let's proceed to step 8:
154 goes into 619 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 552474.0
Subtracting 616 from 619 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
When dividing 30 by 154, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 552474.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
If we divide 300 by 154, we get 1 and a remainder of 146.
Write down 1 as next digit of the result. 
Result so far: 552474.01
Deduct 154 from 300 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 11:
154 can be fit into 1460 9 times, resulting in a remainder of 74.
Write down 9 as next digit of the result. 
Result so far: 552474.019
Subtract 1386 from 1460 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 12:
The number 154 fits into 740 4 times, leaving a remainder of 124.
Use 4 as the next digit of our solution. 
Result so far: 552474.0194
If we take 616 away from 740, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 13:
When dividing 1240 by 154, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 552474.01948
Subtracting 1232 from 1240 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
If we divide 80 by 154, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 552474.01948
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 15:
When dividing 800 by 154, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 552474.0194805
Subtracting 770 from 800 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 16:
When dividing 300 by 154, we get 1 with a remainder of 146.
The number 1 becomes the next digit in our result. 
Result so far: 552474.01948051
Deduct 154 from 300 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The final outcome is 552474.01948051, with a leftover of 1.46e-07.
